Janet Alder won 6.4 percent of the vote standing as the Respect candidate in Tottenham, north London.
Janet has been campaigning for justice ever since her brother, Christopher Alder, died in police custody in April 1998.
Speaking shortly after the result was announced, she said, “Everyone here is buzzing. With us being a new party we’ve done fantastic.
“Tonight has proved that we can make a breakthrough and Respect is a party that’s not going away.
“The campaign has rattled Labour’s David Lammy, who was a junior minister — Labour has been very worried.
“And there were people out there who just couldn’t believe how good we were on the streets. Speaking to people, even from the other parties, they’ve said that.
“This has been an experience for me and for the people here. It’s the start of things to come.”
